Other points of interest

 * 2) The trap in the red key room has a chex armor, simply go through the slimed wall the flemoids came from.

Secrets

 * 1) The bookshelves at the very first chemistry room need to be pressed to open up a secret with a computer area map. (sector 125)
 * 2) The vents in the first gray non-secret area are passable through, simply go through the vent opening and crawl into a transport area, jump into the teleporter pad to get launched back into the very first chemistry room. (sector 231)
 * 3) The vents on the central pillar in the key-locked door hub area have the same effect as the second secret, go through the vent opening to get a chex armor. (sector 149)
 * 4) The room after the full potion room needs to get its right glass cupboard pressed to open up and reveal a zorch propulsor and a zorchpak. (sector 203)

Bugs

 * 1) Some walls are shootable through.
 * 2) There's a common flemoid outside the map.
 * 3) There's a flemoidus cycloptis stuck in the exit room.
 * 4) There are two computer area maps in the map, thus making it impossible to get 100% items, since the player can only pick up one map per level. However, some source ports allow picking up both computer area maps.
